How to Compress Images for the Web

Images often account for most of the downloaded bytes on a webpage. Optimizing images often yields some of the largest byte savings and performance improvements for your website.

Why use Client-Side Compression?

Unlike other tools that upload your photos to a server, WebBox processes your images right here in your browser. This means:

  • Privacy: Your photos never leave your device.
  • Speed: No upload or download waiting times.
  • Security: No risk of server data breaches.

Understanding JPEG Compression

JPEG is a "lossy" compression format. This means it reduces file size by selectively discarding data. By adjusting the Quality slider above, you can find the perfect balance between file size and visual fidelity.
